Organizational memories play a significant role in knowledge management but several challenges confront their use. Artifacts of organizational memory are many and varied. Access and use of the stored artifact is influenced by the user's understanding of these information objects as well as their context. In our work, we use a topic map to represent user cognition of contextualized information. Topic maps allow for access and analysis of stored memory artifacts. We implement the topic map with both a Java client interface and a web interface to access the organizational memory warehouse. The thesis also presents the design and development of this organizational memory warehouse with several simple tools with web access via topic maps. The running warehouse example uses email as the data type.
